What is the rating of cfm in the stock fans?

 

I don't know what the rating is, however; I measured about 1800 CFM pulling through the radiator & condenser with the fans on high. Car was not moving.

 

I have been looking at universal electric fans and fex-a-lite has a dual fans that pull 5500 cfm. I would think that is more than the stock fans . Does anyone run aftermarket fans?

 

There is a big thread on this somewhere, do a little searching it shouldn't be hard to find. I think the final agreement was that while there are a few fans that flow more CFM, the stock fans just fit and seal better so they cool better.
